Since the relative color temperature is actually a black body radiation close to the light color of the light source, the evaluation value of the light color performance of LED light source is not an accurate color contrast, so two light sources with the same color temperature value may still have some differences in the light color appearance. Feng color temperature alone cannot understand the color rendering ability of the light source on the object, or how the object color is reproduced under the light source. The relative color temperature of different light source environment, different light source color temperature, the light color is different: the color temperature is below 3300K, the light color is red to give a warm feeling; There is a steady atmosphere, warm feeling.
